I'd check around with local pottery groups and studios to see if someone else has a similar kiln and get plug info from that person . . . or perhaps they have a manual. Not only do you want the right plug, but also the right size wiring.

i bought today a plug for it and a 20 amp wall plug to wire in so i can use it.

The real big question now is how do i wire the plug onto the cord????? white to black black to red green to blue idk......

The plug i bought i now found out has three terminal hookups (white black and green) while the cord coming form the kiln has green black white and RED.

What do i do????

First, if the kiln must be on a breaker that is 25% larger than the actual draw. So at 19 amps you need a breaker of about 24 amps. That size doesn't exist, so you need to go up to a 30. That means you'll also need a 30 amp breaker. As for the 4 wires, contact Arnold at Paragon or the folks at Euclid's. They have experience with those old kils with odd wiring setups.

To build on that thought from Neil....... it is not just the BREAKER at the electrical supply box that needs to be sized to handle that level of Amperage load, but very importantly ...THE WIRING IN THE WALLS..... must be installed to carry that amperage too. So you likely need an electrician to check/install the circuit for that kiln. You can't just change out the breaker / fuse on the panel and then hook it to the wall socked changed to fit the kiln's plug. If the gauge of the wiring leading from the panel to the kiln wall outlet is not correct.............. you'll eventually start a fire within the wall structure where the wires are routed.

My plan this far is too try to wire it, and then bring it to my school lab where i know they have the proper setup and testing it; then decide whether or not it is worth getting an electrician to come check things out.

Thanks so much for your input. i'll get in contact with somebody who has been "in the business" for a long time to see what is up.
